Running 16.04 server without X unter latest Oracle Virtual Box 5.0.12 on Windows. After issuing 'shutdown -r now' the following boot process is not successfull and hangs with message

If using 'shutdown -h now' and then staring the machine anew from Virtual Box manager, then the system starts as it should. Thus, for short, warm reboot hangs and cold reboot operates as desired. I have the feeling that this behavour was introduced with kernel 4.3, but I cannot swear on it.

Imho, may also be a bug of Virtual Box.

The result of ubuntu-bug linux is attached.
